Description
BACKGROUND OF THE INVENTION
Headsets of the type referred to are well known in the prior art;
nevertheless, the prior art inflight headset for civil aircraft
have the following drawbacks:
1. The ear cushions can be adjusted in height but cannot be rotated
with respect to the perpendicular plane along the length of the
headband. Since the ears of everybody are positioned differently,
the headphones cannot satisfactorily adapt to the needs of
everybody.
2. Each earpiece of the headphones, which is made of flexible
plastics, is in the shape of a mushroom. Each of the earpieces is
inserted into a helicotrema of an ear of an user so that the user
will certainly feel uncomfortable after having worn a short
time.
3. The sound wave must pass an abrupt turn before entering into the
ear cushions, thus resulting in much distortion.
SUMMARY
It is a primary object of the present invention to provide an
inflight headset for civil aircraft which is possessed of a very
smooth passage served to faithfully transmit sound waves.
It is another object of the present invention to provide an
inflight headset for civil aircraft which may be equipped with ear
cushions of different sizes.
It is still another object of the present invention to provide an
inflight headset for civil aircraft of which the ear cushions can
be adjusted in height with respect to the headband by means of two
collars positioned at the ends of said headband in association with
two adjusting rods integral with the main body portions.
It is a further object of the present invention to provide an
inflight headset for civil aircraft of which the ear cushions can
be rotated with respect to the perpendicular plane along the length
of the headband by means of the slots of the adjusting rods in
association with the projections of the headbands.
A better understanding of the present invention will be obtained by
those skilled in the art when the following detailed description of
the best modes contemplated for practicing the invention is read in
conjunction with the accompanying drawings wherein like numerals
refer to like or similar parts and in which:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings and in particular to FIG. 1 thereof, the
inflight headset for civil aircraft according to the present
invention comprises a pair of main body portions (1), a pair of
covers (2), a pair of acoustic pipes (3), a pair of ear cushions
(5) and a headband (4). The headband (4) is provided with a
projection (8) along its length and two collars (6) made of elastic
material. Each of the collars (6) is integrally made with one end
of the headband (4). On the top of each main body portion (1) is an
adjusting rod (7) which is closely fitted into the corresponding
collar (6). Since the collars (6) are made of elastic material,
each adjusting rod (7) may be regulated in height with respect to
the corresponding collars (6). Each main body portion (1) is
connected at one side with a cover (2) and at the opposite side
with an ear cushion (5), and further connected at the lower part
with an acoustic pipe (3) served for transmitting music or the
like. The adjusting rod (7) positioned on the top of the main body
portion (1) is provided with a slot (15) making an angle of
120.degree. along its length. At the middle of the slot (15) is a
protuberance (12) extending along the length of the slot (15),
which will be in contact with the projection (8) when the adjusting
rod (7) is fitted into the collar (6). The protuberance (12) is
designed so that the adjusting rod (7) may be rotated through an
angle of 90.degree. in one direction and an angle of 30.degree. in
the opposite direction with respect to the perpendicular plane
along the length of the headband (4), as shown in FIG. 2.
Referring to the drawings and particularly to FIG. 1, 5 and 6, with
the outer side of the main body portion (1) is engaged the cover
(2) which is possessed of a smoothly curved surface (16). As a
result, the main body portion (1) in association with the cover (2)
will have a very smooth passage, thereby faithfully transmitting
the music or the like; furthermore, the cover (2) is directly
connected to the main body portion (1) and this will facilitate the
assembly and manufacture of the headset. The inner side of the main
body portion is provided with two pins (10) and male screw threads
(9). Each of the pins (10) is adapted to a notch (11) of the ear
cushion (5); consequently, the ear cushion (5) may easily be
mounted to or dismantled from the main body portion (1). If desired
to use smaller ear cushion (52) (as shown in FIG. 6 and FIG. 4), it
is just necessary to engage the ear cushion (52) with the male
screw threads (19) of the main body portion (1).
As stated, the inflight headset according to the present invention
may satisfactorily receive the music or the like and may be
equipped with ear cushions of different sizes as well, and thus is
especially suitable for use in civil aircrafts.
Although this invention has been described with a certain degree of
particularity, it is understood that the present disclosure has
been made by way of example only and that numerous changes in the
detail of construction and the arrangement and combination of parts
may be resorted to without departing from the scope and spirit of
the invention as hereinafter claimed.
